Description

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for securing a level crossing against the entry of vehicles during a warning signal, in particular a device for securing a level crossing.

BACKGROUND OF THE INVENTION

Prior art systems of railway crossing safety devices do not solve any obstacle in any way, for example a vehicle that can get stuck when passing between fallen barriers and thus remain on the rails, thereby causing an accident, collision with the approaching train. All the gates are lowered simultaneously, so that the vehicle which enters the track when the gates are lowered and thus is in the track, its exit being blocked by the gate behind the track which has meanwhile been lowered so that it cannot exit the track. Although the barriers are modified so that the vehicle could violently pass them, but psychologically it discourages some drivers, they leave the vehicle, which leave in the yard, causing the accident Driver does not have information about an unexpected obstacle, and thus detects such an obstacle visually, which is late to prevent an accident. Vehicles are only secured against the entry to the level crossing after the audible warning signal is triggered by the glow of two side-by-side alternating flashing lights, which occurs, and the vehicles occasionally enter the level crossing even after the beginning of the audible warning signal.

SUMMARY OF THE INVENTION

The shortcomings of the prior art are solved by the invention of a vehicle anti-roll-over device in the event of an alarm which, when the barrier system is triggered, first triggers the gates, from the driver's perspective, in front of the rails and then, after an adjustable time, behind the rails. which arrived on the rails just before the barrier in front of the rails, leave the rails in time or are simultaneously triggered, the detector preferably detecting the track space and, when an obstacle for the train is detected, delays or stops the rails behind the rails lifts up to the time of leaving the yard an obstacle when the barriers behind the rails lower.

At the same time, the device sends an alarm to the train control center and / or to the arriving train by means of a wireless link. At the same time, the device preferably triggers an alarm siren and, preferably, a voice message to release the tracks.

Preferably, the camera transmits video from the crossing area to the control room and / or to the train set. The technical device in the train set preferably informs the driver of an obstacle, and this reduces the train speed so that it can brake or slow down the train in good time, or the train control unit automatically controls the train set.

Advantageously, an additional crossing signalization is visible on the access road in front of the barrier system, visible to the approaching vehicles, preferably a one-color to three-color traffic light, similar to a traffic light at a road junction. This will ensure that the vehicle is stopped in red after the start of the warning signal, preferably the ring, before the bolts are lowered. The communication module, which is connected to the control unit which controls the barrier system, transmits data on the crossing situation, in particular, on the possible crossing obstacle and the status of the crossing and safety equipment to the train and train control center preferably directly and / or to the server to which the elected participants have access, which are: train set, dispatching, train control, firefighters, police, other participants. The control unit is connected to a detector and cameras and other sources, from which the status of the barrier system receives the control unit, which preferably controls the barrier system, the signal, the pre-traffic light, the voice unit and the siren.

The control system controlled by the control unit is in the control standstill state when all the barriers in front of the rails and the barriers behind the rails of which the system consists are in the open position. In the process of closing the barrier system, a signal is activated, preferably consisting of a signal of two side by side alternating flashing lights. After an adjustable time, the gates in front of the rails begin to lower. And then after an adjustable time, preferably the anticipated time required to leave the track by a vehicle, the barriers behind the rails are lowered. Barriers are triggered simultaneously or barriers behind the rails are delayed after an adjustable time from the start of the barrier warning system.

Advantageously, the barrier detection sensor in the barrier system area detects the barrier system area on the rails and, upon activation of the barrier warning signal for the detection of an obstacle for a train, for example a vehicle, sends a signal to the control unit controlling the barrier system. , if they are already lowered, it lifts them up until the space on the rails leaves the obstacle. At the same time, the communication module preferably triggers an alarm in the train control station arriving to the train set and, for other selected participants via wireless communication, preferably the communication unit sends alarm and / or camera images directly to the train set via a wireless link.

At the same time, an alarm siren will sound in the region of the barrier system to indicate the need to quickly remove an obstacle such as a vehicle. Preferably, a voice message is produced from the voice unit to release the tracks. Advantageously, the camera transmits a video transmission of the scene of the barrier system space via the communication module to the control room and preferably to the train control unit from which the video is displayed on the driver's monitor. Data and / or voice communication with the control room is carried out wirelessly. The train set upon receiving the obstacle information informs the train set driver visually, preferably on the monitor display or by an indicator light, or acoustically, preferably by a tone or tone from the loudspeaker. The driver reduces the train speed manually or the control unit does so automatically, preferably gradually, so that it can stop in time if the obstacle is not removed. Advantageously, a display is provided on the label with a numerical indication indicating how much time is left to lower the barriers in front of the rails. Preferably, a barrier display is shown on the flag indicating symbolically open barriers, preferably in white or green, which turns red, and the display symbolizes the falling barrier before the barriers in front of the rails begin to fall. Preferably, a light traffic light, preferably one to three-color, visible to vehicles arriving at the barrier system, preferably similar to a three-color traffic light, is located at the location of the barrier and signal system and / or at an optional distance from the front. Simultaneously with the signaling signal, the green light changes to orange and then to red before the gates in front of the rails are lowered. A single-color traffic light signals a red light, a two-color traffic light turns orange. Preferably, the signaling signal is replaced by a traffic light.

Preferably, the communication module sends an alarm and preferably camera shots to firefighters, police, emergency controllers so that they can prepare to exit in the event of a collision in the area in the barrier system.

The camera sends the police all the necessary data, such as the vehicle registration number, for eventual recourse to a party, such as the driver of the vehicle, that caused an obstacle to be placed on the track. If the obstacle is a vehicle that leaves the barrier area without an accident, the police are preferably equipped with a road display controller instructing the vehicle to wait for the arrival of the shelf, for example to descend the parking lane and wait for the police to arrive there.

Advantageously, the communication module sends data to a server to which selected participants have access, for example, a train control center, train set, via the Internet.

The selected participants have access to the situation data of all barrier systems which are equipped with a communication module and associated units for sensing and / or detecting obstacles and / or sensors, preferably formed by cameras. Advantageously, a train set detector is provided on the track which, when detecting a train, preferably at a greater distance than a visual one, warns against a level crossing by a horn that the train is arriving and preferably a voice announcement announces an arriving train. Advantageously, a camera system preferably comprising multiple cameras of the camera system upstream of the barrier system is provided on the track, emitting a live train arriving, preferably when switching to the cameras the train is passing by to the monitors visible to the incoming drivers to the barrier system for the psychological etiquette to prevent entry into the barrier system area at the audible warning signal. Preferably, the distance of the train set from the level crossing is shown. Advantageously, the incoming train is also transmitted to the dispatching server and other subscribers via a wireless link or a live view of the incoming train.

The selected participants are equipped with a display device, preferably comprising a computer with a monitor, which can be adapted for one or preferably multiple screen displays to view multiple barrier systems at a glance. Thus, a train driver can watch live barrier systems sensed by cameras that are on the route he is traveling ahead of time.

The anti-theft alarm device comprises a control unit which controls the barrier system comprising a signal The control unit controls the barriers, the semaphore, the voice unit, the alarm siren and receives information from the barrier detection sensor in the area of the barrier system, camera and other sources of information; on the basis of these controls the voice unit

It sends information via the communication module to the server to which selected participants have access such as a train set, train traffic control center, fire brigade, other participating police, which advantageously control the road display. The communication module is adaptable for direct connection with selected participants.

The level crossing device contains a right area, which is detected by a right sensor system. If this sensor system detects a right obstacle in it, it prevents the right barrier behind the rails from lowering. If the control unit is already partially or fully lowered, it will only raise and allow it to start when the obstacle is not detected by the sensor system. The position of the "left" bar "right" is taken from the S direction. The position "in front of the rails" and, 7a rails "is taken from the driver's point of view in the direction of his arrival at the level crossing. Similarly, the left sensor system works with sensors, detecting the obstacle, on the left. The barrier system comprises a right behind the rails, a left barrier before the rails, a right barrier before the rails and a left barrier behind the rails controlled by the control unit. sensors do not detect an obstacle to trigger all the barriers simultaneously, or barriers behind the rails, with a delay.

The right sensor system is preferably comprised of a plurality of sensors, preferably a first right in front of the rails, a second right in front of the rails, a first right behind the rails and a second right behind the rails, which detect passing vehicles also when the gates are raised. whether the ringtone is activated or not. In case there is no match in the detection of all sensors, the barrier system will trigger an alarm in the train control center through wireless communication to eliminate the fault. The left sensor system works similarly.

The level crossing device preferably comprises a traffic light, located at an optional distance, e.g. 50 m, from the barriers.

The traffic light is preferably a tricolor traffic light or a two-color traffic light or a light signal of two side-by-side alternating flashing lights.

A traffic light at an optional distance in front of the barriers with a "STOP" signal stops vehicles arriving at the barriers even at the front of the barriers at the time of the hazard warning signals before the barriers are triggered. Then the control unit switches the signaling to "LEFT". The vehicles can continue to travel to the latches already in place to prevent them from entering the crossing.

Thus, the level crossing detection unit detects the beginning of the warning lights signaling with an optical sensor and the triggering of the bolts by the sensor of the triggering of the bolts or of both phenomena simultaneously by the camera sensor. Alternatively, the detection unit detects the alarm ring preferably by an acoustic sensor.

The activation of the "level crossing warning lights", eg by alternating blinking of two red lights, is detected by this detection unit, which is used in the event that a direct electrical connection of the link to the railroad warning device is not possible or desirable; signaling and ringing connected directly to the electrical crossing signaling equipment. In the case of using this detection unit, preferably constituted by an optical sensor, the unit for transmitting the warning light activation information is connected to the control unit of the signaling device by a link which is optionally implemented by conductors and / or wirelessly. It transmits a signal to activate a warning light to the control unit which ceases signaling to "stop, preferably a red light of light signal, preferably consisting of three-color traffic light information on starting gates transmits the detection unit ₁ is preferably formed with a sensor detecting the running of gates, a control unit which puts the semaphore back to "LEAVE", preferably with a green light, which preferably follows the orange light

If the traffic light consists of a two-color traffic light, it is red when it is switched to “STOP”. When it is set to "LEAVE" it flashes with an orange signal light or does not indicate. If the traffic light is a light signal, when it is switched to "STAND" it flashes alternately with red lights placed next to it and when it is switched to "LEFT" it is switched off.

The level crossing detection unit is preferably formed by an optical and / or acoustic sensor and / or a camera sensor and / or a lowered barrier detection sensor. At the beginning of the ring, the traffic light is set to "STOP", at the end of the ring to "LEAVE".

The warning light sensors, optical and acoustic, are preferably located directly on the barrier device of the bolts or on a separate forward sensor column.

Preferably, the maximum distance of the traffic light to the barrier is chosen so that vehicles at the maximum permitted speed, for example 50 km / h, travel this distance with a margin so that it preferably arrives at the barrier just after the warning lights flash when the barrier is still up. therefore, in the event that vehicle drivers fail to comply with the traffic rules and drive into the crossing despite the activation of the hazard warning lights, they should have enough time to safely and safely pass the crossing before the gates are lowered. The distance is preferably determined according to the time preceded by the warning signal prior to the opening of the barriers, which begins approximately 30 seconds after the crossing warning lights flash. Just before the barriers are triggered, no more cars will pass through the barriers, as they are stopped by a traffic light in advance

Although the control unit will reset the traffic light to "OFF" after the barriers have been triggered, the vehicles, if originally stopped, can now arrive at the barriers already triggered

The next semaphore cycle to "STOP" is initiated the next time the warning lights or ringtones are activated.

Optionally, the traffic light is set to "OFF" only when the hazard warning lights flash, that is to say, lift the gates and not when the gates are lowered. This signaling device is also suitable for unprotected level crossings where the barriers are not installed.

Advantageously, a deceleration section with a traffic sign is placed in front of the traffic light. Maximum speed, for example 30 km / h. Advantageously, a traffic light sign is placed downstream of the deceleration section. End of all prohibitions, preferably a traffic light that terminates the speed limitation. This traffic sign is preferably activated depending on the activation of the traffic light signs. with traffic light. The traffic sign is located on a separate post or on a post of a traffic sign. Crossing with barriers.

The deceleration section of the barrier crossing is preferably implemented to slow down the traffic of vehicles before the activated barrier. The level crossing warning lights are activated and start to signal, preferably by blinking, the onset of the barriers, and at the same time the selectable number of traffic lights "Maximum speed limit" lights up and displays an adjustable speed, for example 30 km / h. They are optionally deactivated when the bolts are started or after the hazard warning lights have been deactivated.

In order to highlight the approach of the barrier opening, the traffic signs are preferably illuminated and / or are preferably provided with orange signaling lights, and, preferably alternately flashing, at the same time as the warning lights indicate the upcoming barrier opening.

The pre-crossing signaling device is preferably also used for crossings without barriers to prevent entry to the crossing at the time of arrival and crossing of the train, which is signaled by the control room signal to the control unit which controls the signaling devices for stopping and decelerating the vehicles.

Optionally, the traffic light is preferably formed by two red signal lights of two side-by-side alternating flashing lights, which are activated for the "STOP" signal and switched off for the "OFF" signal.

Preferably, a semaphore countdown timer and a traffic sign highlighting the semaphore with inscriptions and / or symbols, such as "STOP, 20s" as a countdown timer countdown, are placed on the traffic light, and CAUTION RED, with driver information, it is preferably activated when the hazard warning lights are activated.

Advantageously, a camera model is installed in the route to achieve greater driver discipline. This camera can be replaced by a real camera

A simplified version of the level crossing device is a completely omitted deceleration section.

The signaling device for stopping vehicles before crossing may be supplemented by a combined deceleration section, by means of which the deceleration is realized both by the visualization of the activated traffic sign reading when the hazard warning lights are triggered, but also by the radar unit, preferably with a radar unit in front of the traffic sign , if it registers a vehicle which exceeds the maximum permissible speed displayed on it and which is adjustable. Advantageously, a traffic sign "End of all prohibitions" is located behind the traffic sign. Advantageously, there is a camera speed measuring camera model which is interchangeable with a real camera, so that there is an optional saving compared to when a real camera is fitted, since the driver does not know when the camera is deployed. For greater effect, when the vehicle is passing, the light on the dummy of the camera flashes to give the impression that it is recording

Optionally, the combined deceleration section can be fitted multiple times to increase the effect. It can be used in road traffic at crossings with or without barriers. In this case, the traffic sign is activated only from the radar unit, which is also located in the traffic sign.

Preferably, the combined deceleration section is followed by a stop section whose radar unit converts the traffic light to "STOP", preferably red, when the vehicle arrives at a speed above the currently valid adjustable value, even though the crossing warning lights are not activated. When activated, they will automatically reset this to “STOP”.

The radar unit is preferably adapted to be adjusted to either a speed not reduced, for example, 50 km / h, or reduced, for example, 30 km / h, when the traffic sign is activated and the traffic sign is not activated or not deployed. The speed on the radar unit is adjustable to a speed that is selectable above the highest speed limit to achieve the selected speed tolerance.

The stop section can be used in traffic even without barriers. In that case, the traffic light is only a radar unit. When the hazard warning lights are activated, the traffic sign is not activated to maintain a valid speed reduction of, for example, 30 km / h. The camera mock-up is preferably also placed on the light semator, preferably on the traffic sign post. Advantageously, dummies indicating speed measurements are placed in front of the dummies to increase the efficiency of the dummies. The display of the radar unit located in front of the traffic sign preferably, besides the current measured speed, also displays the sign slow to a certain speed, for example 30 km / h, referring to the speed indicated on the traffic sign that follows.

The model-interchangeable camera captures not only the speed of the vehicle, but also the non-stopping of the red traffic light.

An additional barrier to the passage of the driver to the bolts can be applied if it has passed the red traffic light. The detector formed by a camera or a sensor then controls the traffic light at the edge of the lane, no traffic sign, and / or the commanded traffic light, where the driver preferably sees the waiting sign at the police and it is prevented by a barrier, preferably remotely controlled. Preferably, the communication unit is adapted for voice communication with the surveillance desk and / or the police.

The level crossing device according to the invention may also be applied to passageways when the hazard warning lights flash with the help of traffic lights at a junction and a T-junction. '

Traffic lights control intersections in the usual way by means of a control unit to which they are connected by means of joints. When two side-by-side alternating intermittent traffic lights control the traffic lane .A, from which the barrier is approaching, they switch to "STOP" mode, in which they are lit red, and if they are lit in a different color, hay changes red in a prescribed manner, that is, from green to orange. This prevents the "A" lanes from passing through lanes. The J3 'lane traffic lights leading from the barriers turn green to allow the vehicles to leave and not create columns that could block the crossing.

The activation of the light signal is preferably detected by a warning light sensor which is connected to the control unit by a link.

The traffic lights are switched from "STOP" mode to the normal junction control mode when the barrier is triggered, preferably upon detection by the barrier detector detection sensor and / or the signal light sensor indicating the end of light activation, the information being transmitted after the connection

Vehicle sensors detect vehicles driving the lane, J3 'from the barriers, and, in the case of a detected vehicle, switch the junction control so that these vehicles preferably have a green light so as not to form traffic-blocking columns.

The vehicles are stopped in the "STOP" mode only for the duration of the signal activation until the latches close, ie for a relatively short time, about 20 seconds.

Then the junction control switches to normal operation and the vehicles cross the controlled junction to the already-opened gates so that they cannot pass over when the hazard warning lights flash.

Vehicles running between intersections and crossings at the time of signal activation and "STOP" mode arrive at the very beginning of activation of the hazard warning lights, so if they fail to respect them, they have about 20 seconds for a relatively safe barrier crossing before they start. Other vehicles for which crossing would be risky are already held by traffic lights.

Or the traffic lights do not control the intersection at the time of the lift barriers, the traffic lights are off or flash orange. The turn signal semiconductor, "B", is preferably not installed and the vehicles in this lane are constantly free to pass.

If the signal is activated, the color of the lights will change from orange flashing to red in a preset manner until the barrier is triggered, turning back to flashing orange.

It is preferred to provide a crossing safety device with increased safety which is achieved by combining the vehicle stopper until the barrier is triggered, preferably with a deceleration section using road signs changing the maximum permissible speed, and preferably using a voice unit. Traffic signs varying the maximum permissible speed are preferably illuminated and are preferably formed by a set of LEDs or in a mechanical design, preferably with flip-flops.

The vehicle stop for the time until the barrier is triggered is a command signaling preferably consisting of a tricolor traffic light or an alternating flashing traffic light. Preferably, a camera recording the vehicle that has gone red is located on the vehicle stop post.

The stopper for vehicles exceeding the maximum permissible speed is preferably a tricolor traffic light and is activated when the vehicle exceeds the maximum permissible speed given by the road sign changing the maximum permissible speed or, in the absence of the sign, by the decree or by another previous road sign. and the stopper is preferably deactivated when the bolts are lowered.

Advantageously, a deceleration section is provided upstream of the vehicle stop until the barrier is provided, preferably with a traffic sign changing the maximum permissible speed or more wdl - traffic signs changing the maximum permissible speed, preferably two for example 30 km / h and 15 km / h. This road sign changing the maximum permissible speed, or a combination thereof, decelerates the vehicles to such a speed that the vehicles located in front of the road safety signal, from the beginning of the hazard warning signal to the opening of the bolts, preferably during the warning signal. , could not enter the crossing before the barrier is triggered, and this is ensured by the fact that the road signs changing the maximum permissible speed are activated at the beginning of the ringing of the railway crossing barrier system or when the crossing warning light is activated. of the railway crossing barrier system, ie when the barrier is lowered.

The distance between the road signs changing the maximum permissible speed as well as the maximum speed they allow is preferably adjusted according to the ringing time until the bolts are released so that vehicles which left at the time of activation of the road signs changing the maximum permissible speed and the maximum speed allowed to reach latches after their launch.

Thus, for example, the first road sign changing the maximum permissible speed, preferably 30 km / h, is preferably located, for example, at a distance of 350 m from the railroad crossing barrier system, to initially slow down the vehicles from the speed they arrive. The second road sign changing the maximum permissible speed for the final deceleration, preferably 15 km / h, is preferably located at a distance of 240 m from the railroad crossing barrier system. The distance of the second maximum speed limit traffic sign from the railroad crossing barrier system and the maximum speed limit value of this maximum speed limit traffic sign shall be determined by calculation taking into account the time from the start of the warning signal to the barrier start, which is usually 30s to 45s. the vehicle traveling at this maximum speed limit given by the road-speed-changing sign reached the barriers only after they were started, and the vehicles traveling at unabated speed reached the barriers for a sufficiently long period of at least 1 Axis before starting the barriers. she could run over it without any trouble. Thus, for example, the journey time for which a vehicle traveling at 50 krvvh travels a distance of 240 m is approximately 17s. A vehicle traveling at this unabated speed would travel this distance from the second traffic sign changing the maximum permissible speed in less than the time from the beginning of the alarm to the opening of the bolts, eg 30s, and if 240 m from the level crossing , it would arrive to it even 13s before their start, ie in the case of illegal entry to the crossing would have enough time to safely pass the crossing before starting the race .. On the other hand, the driving time for a vehicle traveling at reduced speed 15 km / h travel distance 240 m is approximately 58s. A vehicle traveling at this reduced speed and located at the above-mentioned distance from the level crossing at the time of the start of the alarm would reach the level crossing only after the gates have been lowered.

The system of the signaling device is preferably provided with a traffic sign "Light signals", preferably illuminated by means of LEDs. These "Traffic Signs" traffic signs can be installed more than one in succession, for example two, being located on columns of traffic signs changing the maximum permissible speed. The LEDs of the traffic light "Light signals" are preferably switched on when the crossing warning signal is triggered, and are preferably switched off when the bolts are triggered, i.e. they are preferably activated during the ringing period.

The level crossing device is preferably provided with a stop light signal, "End of all prohibitions", preferably light or mechanical with slats and preferably located on the traffic light post "Light signals" at a distance of preferably 80 m and 160 m from the rail barrier system crossing. The “End of all prohibitions” traffic sign is activated when the barriers are lowered and allows vehicles to reach the barriers lowered at a reduced speed.

The level crossing device preferably comprises a voice unit preferably located on a vehicle stop post, i.e. at a distance of about 80 m from the level crossing, and the voice unit preferably reports a text, e.g. The signaling device system preferably also comprises a second voice unit, preferably located 80 m in front of the first voice unit. The voice units are preferably switched off when the vehicle sensor detects that the vehicle has stopped before the first command signaling. Preferably, an acoustic sensor is also provided near the level crossing, preferably on the camera mock-up post, which serves to detect the warning ring of the level crossing security device and which preferably comprises a directional microphone. Advantageously, on this post there is also a traffic sign, the end of the speed measurement 'and an omnidirectional transmitter for transmitting a signal for at least one of the traffic signs' traffic signals', the vehicle stop until the bolts are triggered. The signal transmitted by the omnidirectional transmitter is received by receivers preferably located on the columns of the above-mentioned elements, the state of which is controlled by this signal. Advantageously, a traffic sign " Speed Measurement "

The level crossing device preferably comprises signaling lights in the roadway to highlight the vehicle stopper until the latch is lowered. The signaling lights in the roadway are preferably located in the roadway at the vehicle stopping position and are activated with it for the time until the bolts are lowered, and are preferably bounded by a traffic sign.

This design ensures multiple securing of the railway crossing barrier system. Advantageously, the first safety measure consists in decelerating the vehicles with a deceleration section using road signs changing the maximum permissible speed from the beginning of the warning system ringtone to the opening of the barriers so that the vehicles cannot reach the crossing before the barriers are lowered. Preferably, the second safety measure consists in stopping the vehicles by the vehicle stopper until the bolts are lowered. Preferably, the third safety measure consists in locating a vehicle stopper exceeding the maximum permissible speed.

Preferably, the fourth safety measure consists in emphasizing the stopping of the vehicles for the time until the gates are lowered with a light sign preferably provided with the word "STOP" and preferably with a countdown timer. Advantageously, the fifth safety measure consists in highlighting the vehicle stopping device until the barrier is triggered by the voice unit. All of the above safety measures are effective separately to ensure crossing safety and optionally applied.

The acoustic sensor detects the acoustic signal of railway crossings. It is preferably provided by means of a directional microphone, preferably located in the focus of the dish directed to the railway signaling device, and the acoustic sensor is preferably tuned. This means that the characteristics of the microphone and its sensitivity in conjunction with the evaluation circuits are set to the characteristic and energetically maximally represented frequencies occurring in the audible warning signal of the level crossing, preferably for each level individually.

This ensures that the detector only responds to this audio signal. Tuning is performed automatically at the instruction of the operator by means of a microprocessor, which in the respective mode of operation evaluates the audible signal of the given railway warning signaling device and sets the characteristics of the evaluation circuits. Sound evaluation is based on Fourier signal development to individual components and their content is compared with the sample to which the acoustic sensor is tuned. When sufficiently matched, the sensor sets its output signal to a state with the meaning that the level crossing warning sound signal has been detected and another signaling according to the present invention is provided providing increased level crossing safety.

Railway audio signals contain at least one, but mostly two dominant frequencies, but there may be more. The audible warning device located on the far side of the passage for the opposite direction also touches the downstream side of the level crossing. This makes it possible to tune the acoustic sensor only to the facing or both sides, which further increases the level crossing safety, since further signaling will occur on both sides even in the event of a failure on the rail equipment on one side.

A directional microphone that senses a railroad audible warning signal at a level crossing is directed to the level crossing and placed in the parabola, and a signal therefrom is applied to an amplifier, preferably differential input, and further converted to a digital signal in the A / D converter. This signal is evaluated in a microprocessor and compared to a recorded sample characteristic of the subject crossing. In the case of a match, the signal at the respective microprocessor output has a value that expresses the match preferably, wherein the microprocessor output signal can have a significance of 1 after deterioration, preferably lasting for an adjustable reception time of the tuned signal after an adjustable time from the beep. This signal is used to activate other devices, either wired or wireless via an omnidirectional transmitter, so that all crossing security devices fitted with the receiver can use the signal.

Alternatively, the transmitter is adapted for duplex communication with a receiver also adapted for duplex operation over a mobile network, preferably a local WIFI network. This allows you to collect device status information from status detectors. These are preferably registered in the memory of the microprocessors and / or preferably sent over the remote network, preferably the mobile operator network to the monitoring center server and from there preferably to the selected subscribers. Preferably, the device comprises security sensors protecting the device from theft from an industrial camera, which are transmitted to a surveillance console, which can preferably address a potential thief at the time of the crime and detach it with a voice unit.

DETAILED DESCRIPTION OF THE INVENTION

Giant. Figures 1 and Detail 1 in the S and Detail 2 directions show the barrier system of the level crossing device, the roadway 39 and the barrier system thereon in the idle state of the control unit 6, where all the barriers 2p are in front of the rails and of which the system consists, in the open position. In the process of closing the barrier system 1, the beacon 3 is activated, preferably consisting of a signal 206 of two side-by-side alternating flashing lights. After an adjustable time, the barriers 2p in front of the rails will start lowering. After an adjustable time, preferably the expected time required to leave the track by a vehicle, the barriers 2z are lowered behind the rails.

Giant. 3 illustrates a level crossing device with a barrier system 7 in which the right-hand space 35 is detected by the right-hand sensor system 48. In the event that this sensor system detects an obstacle 41 on the right, it prevents the right-hand barrier 60 from lowering behind the rails. In case it is already partially or fully lowered, the control unit 6 shown in Fig. 1 will lift it and allow it to start only when the obstacle 41 is not detected by the sensor system 48. The position of the latches "left" "right" is viewed The 'forward' and '7a' positions are taken from the driver's point of view in the direction of his arrival at the level crossing.

In case there is no consensus in the detection of all sensors, the barrier system triggers an alarm in the train control center 11 via the wireless communication 13 to eliminate the fault, as shown in Fig. 1.

Similarly, the left sensor system 54 operates.

Giant. 4 and its detail 1 show a system of a signaling device for stopping vehicles in front of a rail system 1 of a railway crossing barrier, preferably comprising a traffic light 15 located at an optional distance, e.g. 50 m, from the barrier 2.

Preferably, the traffic light 103 is a tricolor traffic light 204 or a two-color traffic light 205 or a light signal 206 of two side-by-side alternating flashing lights.

The traffic light 103 located at an optional distance in front of the latches 2 with a "STOP" signal stops the vehicles arriving at the latches 2 ahead of them at the time of the warning lights 106 crossing before the latches 2 are triggered. she couldn't enter the level crossing. Then the control unit 6 switches the signaling to "LEAVE". The vehicles can continue to travel to the latches already in place to prevent them from entering the crossing.

Thus, the level crossing detecting unit 73 detects the start of the warning lights 106, preferably the optical sensor 211, and the triggering of the bolts 2 by the detecting detector or both at the same time by the camera sensor 212. Alternatively, the detecting unit 73 detects the alarm ring preferably by an acoustic sensor 213.

The activation of the "crossing warning lights 106", eg by alternating flashing of two red lights, is detected by this detection unit 73, which is used in the event that a direct electrical connection of the connection 105 to the railroad warning device 106 is not possible or desirable. 108 is connected directly to the level crossing electrical signaling device for alarm and ring information. When using this detection unit 73, preferably consisting of an optical sensor 211, the warning light activation information transmission unit is connected to the control unit 108 of the signaling device via a link 105, which is optionally implemented by conductors and / or wirelessly. The latter transmits the warning light activation signal 106 to the control unit 108, which sets the signaling to "STOP", preferably by the red light of the traffic light 103, preferably consisting of a tricolor traffic light 204. 121, detecting lowered gates, the control unit 108, which sets the semaphore 204 back to "LEAVE", preferably with a green light, which preferably follows an orange light. If the traffic light 103 is formed by a two-color traffic light 205, it lights up with a red signal light when it is switched to "STOP". When it is set to "LEAVE" it flashes with an orange signal light or does not indicate. If this traffic light 103 is formed by a light signal 206, it flashes alternately with red lights placed next to each other when it is switched to "STOP" and it is switched off when it is switched to "LEFT".

The level crossing detection unit 73 is preferably comprised of an optical sensor 211 and / or an acoustic sensor 213 and / or a camera sensor 212 and / or a sensor 121 for detecting lowered gates. At the beginning of the ring, the traffic light 103 is set to "STOP", at the end of the ring to "LEAVE".

The warning light sensors 107, 211 optical and 213 acoustic, are preferably located directly on the barrier rail device or on a separate forward sensor column 214.

The maximum distance 109 of the traffic light 103 from the gates 2 is preferably selected so that vehicles at the maximum permitted speed, for example 50 km / h, travel this distance with a margin so that they arrive at the gates 2 preferably just after the warning lights 106 start flashing. when the gates 2 are still up, so that if the vehicle drivers do not comply with the traffic rules and enter the level crossing despite the activation of the hazard warning lights 106, they will have enough time to safely and safely pass the crossing before the gates are triggered. The distance 109 is preferably determined according to the time preceded by the warning signal prior to the opening of the barriers 2, which starts approximately 30 seconds after the flashing of the warning lights 106 has started. Just before the gates 2 are triggered, no more cars will pass through the gates, as they are stopped by the traffic light 103 in advance.

Although the control unit 108 switches the traffic light 103 to "LOAD" after the opening of the bolts 2, the vehicles, if initially stopped, can now arrive at the latches already in operation 2. The next cycle of changing the traffic light 103 to "STOP" is initiated the next time warning lights 106 or ringtones.

Optionally, the traffic light 103 is set to "OFF" only when the warning lights 106 flash, i.e., after the gates have been lifted and not when the gates have been lowered. This signaling device is also applicable to unprotected crossings where the gates are not installed.

Advantageously, a deceleration section 118 is provided in front of the traffic light 103 with a traffic sign 110, "Maximum permissible speed", for example 30 km / h. Advantageously downstream of the deceleration section is a traffic sign 120, End of all prohibitions, preferably a traffic sign which terminates the speed limit. Preferably, this sign is activated depending on the activation of the "Maximum speed limit" traffic light signs 110, preferably activated together with the crossing warning lights 106 or the traffic light 103. The traffic light 110 is located on a separate post 112 or traffic post 113 Marking 102 "Crossing with barriers".

The barrier barrier section 118 is preferably implemented to slow down the traffic of vehicles before the activated barrier 2. The hazard warning lights 106 are activated and begin to indicate preferably the flashing of the barrier opening by flashing and at the same time the optional number of traffic lights 110 is activated. “That lights up and displays an adjustable speed, such as 30 km / h. They are optionally deactivated when the bolts 2 have been lowered or the hazard warning lights 106 have been deactivated.

To accentuate the impending lowering of the barriers 2, the "barrier crossing" traffic signs 102 are preferably illuminated and / or are preferably provided with orange signal lights 111, and, preferably alternately flashing, simultaneously with the warning lights 106, indicate the upcoming lowering of the barriers.

The pre-crossing signaling device is preferably also used for crossings without barriers to prevent access to the level crossing at the time of arrival and crossing of the train, which is signaled by the control room control unit 108, which controls the signaling devices for stopping and decelerating the vehicles.

Optionally, the traffic light 103 is preferably formed by two red lights of the signal 206 of two side-by-side alternating flashing lights, which are activated for the "STOP" signal and switched off for the "OFF" signal.

Preferably, a semaphore 103 is provided with a countdown timer 200 and a light sign 201 highlighting the semaphore with inscriptions and / or symbols, for example, "STOP, 20s" as a countdown timer countdown 200, and CAUTION RED CAMERA with information. for the driver, wherein the sign is preferably activated when the hazard warning lights are activated.

Preferably, a dummy of camera 117 is installed in the route, by means of which greater driver discipline is achieved. This camera can be replaced by a real camera.

Giant. 4 det. 2 shows a simplified variant of the signaling device for stopping vehicles before the crossing barriers 2, where the deceleration section 118 is completely omitted.

Giant. 5 shows a signaling device for stopping vehicles before crossing, supplemented by a combined deceleration section 122, by means of which the deceleration is realized both by the visualization of the activated traffic sign 110 when the hazard warning light 106 is triggered by the hazard light sensor 107; units in front of the traffic sign 110, if it registers that the vehicle exceeds the maximum permissible speed displayed thereon, which speed is adjustable. Advantageously, a traffic sign 120 "End of all prohibitions" is located downstream of the traffic light 110. Advantageously, there is a vehicle speed camera mock 117 which is interchangeable with a real camera, so that savings are optionally achieved over the case where a real camera is mounted because the driver does not know when each camera is deployed. For greater effect, when the vehicle is passing, the light on the camera dummy 117 flashes to make it appear to be recording.

Optionally, the combined deceleration section 122 can be fitted multiple times to increase the effect. It can be used in road traffic at crossings with or without barriers. In this case, the traffic light 110 is only activated from the radar unit 116, which is also located in the traffic light 110.

The combined deceleration section 122 is preferably followed by a stop section 115 whose radar unit 116 converts the traffic light 103 to "STOP" by the control unit 108, preferably red, when the vehicle arrives at a speed exceeding the currently valid adjustable value, even though warning lights 106 level crossing are not activated. When activated, they will make this change to “STOP” automatically.

The radar unit is preferably adapted to be set to either a speed not reduced, for example 50 km / h, or reduced, for example 30 km / h, when the traffic sign 110 is activated and the traffic sign 120 is not activated or not deployed. The speed on the radar unit 116 is adjustable to a speed that is selectable by a value higher than the highest permissible speed to achieve the selected speed tolerance.

The stop section 115 is usable in traffic even without barriers 2. In this case, the traffic light 103 is only a radar unit 116. When the warning lights 106 are activated, the traffic light 120 is not activated to maintain a valid speed reduction, for example 30 km / h.

The camera dummy 117 is preferably also positioned on the traffic light 103, preferably on the traffic sign post. Advantageously, dummies indicating speed measurements are placed in front of the dummies to increase the efficiency of the dummies. In the radar unit display 119 located in front of the traffic sign 120, in addition to the current measured speed, preferably the sign slows to a certain speed, for example 30 km / h, referring to the speed indicated on the traffic sign 110 that follows.

Camera 117 '. replaceable by a dummy, it captures not only the excessive speed of the vehicle, but also the non-stop at the red traffic light 103.

Giant. 6 illustrates a further barrier to the passage of the driver to the bolts 2 in the case of passing through the red traffic light 103. The detector 136 formed by a camera or a sensor at the edge of lane 134 preferably controls the traffic sign 131. The commanded direction of travel, where on the parked lane 133, the driver preferably sees the police waiting sign 135 and is prevented from leaving the barrier 130, preferably remotely controlled. Preferably, the communication unit 139 is adapted for voice communication with the supervisor and / or the police.

Giant. 7 illustrates an example of a device for securing a level crossing against flashing warning lights by means of traffic lights located at the junction and junction 70 of the "T" type.

The traffic lights control intersections 69 in a conventional manner by means of the control unit 6 with which they are connected by means of connections 105. When the signal 206 of two adjacent intermittently intermittent traffic lights 15, which control lanes "A" from which the barriers 2 arrive, switch to "STOP" mode, in which it glows red and, if it glows in a different color, changes to red in the prescribed manner, ie from green to orange. This will prevent the passage of lanes “A” to the barriers From the lane traffic light, 3 ”leading from the barriers will turn green so that the vehicles can leave and no columns can form that could block the crossing.

The activation of the light signal 206 is preferably detected by a warning light sensor 107 which is connected to the control unit 6 by a connection 105.

The traffic lights are switched from "STOP" mode to the conventional junction control mode when the barrier is triggered, preferably upon detection by the barrier detecting sensor 121 and / or the warning light sensor 107 signaling the end of light activation, the information being transmitted over the link 105.

Vehicle sensors 71 detect vehicles in the lane 3 'of barriers 2, and, in the case of a detected vehicle, switch the junction control so that these vehicles preferably have a green light to avoid the formation of traffic obstruction.

The vehicles are stopped in the "STOP" mode only for the time the signal 206 is activated, until the gates close, ie for a relatively short time, about 20 seconds.

Then the junction control switches to normal operation and the vehicles pass the controlled junction already to the latches 2 so that they cannot pass over when the hazard warning lights flash.

Vehicles moving between intersections and crossings at the time of signal 206 and "STOP" activation arrive at the very beginning of the hazard warning lights, so if they fail to do so, they have about 20 seconds for a relatively safe barrier crossing before they start. . Other vehicles that would be risky to cross are already detained by traffic lights 15.

Or the traffic lights 15, at the time of the lift gate 2, do not drive the intersection, the traffic lights are off or flash orange. The direction control traffic light ..B is preferably not installed and the vehicles in this lane are constantly free to pass.

If the signal 206 is activated, the color of the lights will change from orange flashing to red in a preset manner until the latches are triggered, turning back to flashing orange.

Giant. 8 illustrates a preferred embodiment of a level crossing device with a system of signaling devices for stopping vehicles before a railroad crossing barrier system with increased safety, which is achieved by combining vehicle stopper 83 to form gates, preferably with a deceleration section 118 using traffic signs 155 varying the highest the speed limit, and preferably using the voice unit 24. Traffic signs 155 varying the maximum speed limit are preferably illuminated and are preferably formed by a set of LEDs or in a mechanical design, preferably with flip-flops.

The vehicle stop 83 for the time until the barrier is triggered is constituted by a command signaling 323 preferably consisting of a tricolor traffic light 204 or an alternating flashing traffic light 34. The signaling is activated at the moment of the vehicle alarm signaling. for the duration of the warning ring. Preferably, a vehicle recording camera 226 that has traveled to red is disposed on the vehicle stop post 83.

The vehicle stopper 84 is preferably a tricolor traffic light 54 and is activated when the vehicle exceeds the maximum permitted speed given by the traffic sign 155 changing the maximum allowed speed or, in the absence of the activated, by the decree or other speed. the preceding traffic sign and the stopper 84 is preferably deactivated when the bolts are lowered

2.

Advantageously, a deceleration section 118 is provided upstream of the vehicle stopper 83 until the barrier is triggered, provided with preferably a maximum speed limit road sign 155 or a plurality of maximum speed limit signs 155, preferably two, for example, 30km / h and 15km / h. This road sign 155, or a combination of these, provides a deceleration of the vehicle to a speed such that the vehicles located between the start of the hazard warning light 106 and the barriers are triggered, preferably during the alarm signaling. - β "," _t "., crossing, before the traffic sign, not to enter the crossing before starting gates 2, and it is ensured that the traffic signs 155 changing the speed limit is preferably activated at the beginning of the Ring railway system j barriers of the level crossing or, at the moment of switching on of the level crossing warning light 106, and preferably, at the end of the ringing of the rail system 1, the level crossing gates are switched off, i.e. when the gates 2 are lowered.

Preferably, the distance of the maximum speed allowed traffic signs 155 as well as the maximum speed they allow is adjusted according to the ringing time until the bolts are triggered so that vehicles that traveled at the time of activation of the maximum speed allowed traffic speed 155 permits, arrived at the barriers after their launch.

Thus, for example, the first traffic sign 155 changing the maximum permissible speed, preferably 30 km / h, is preferably located, for example, at a distance of 350 m from the railway crossing barrier system 1, to initially slow down the vehicles from the speed they arrive. The second road sign 155 changing the maximum permissible speed for the final deceleration, preferably 15 km / h, is preferably located at a distance of 240 m from the railroad crossing barrier system 1. The distance of the second maximum speed limit traffic sign 155 from the railroad crossing system and the maximum speed limit value of this maximum speed limit traffic sign 155 is determined by calculation with respect to the time from the start of the alert ring to the start of the latches, which is usually 30s to 45s. so that the vehicle traveling at this maximum speed limit given by the 155 maximum speed limit road will arrive at the bolts only after they have been started, and the vehicles traveling at unabated speed will arrive at the bolts sufficiently long, at least 10s, before starting. it could still run over without warning. Thus, for example, the driving time for a vehicle traveling at 50 km / h to travel a distance of 240 m is approximately 17 seconds. A vehicle traveling at this non-reduced speed would travel this distance from the second maximum speed warning sign 155 in less than the time from the start of the alarm to the opening of the bolts 2, for example 30s and if it were 240 m from the alarm. railway crossing, it would come to him even 13s before their start, so in the case of illegal entry to the crossing would have enough time to safely pass the crossing before starting the race. On the other hand, the travel time for a vehicle traveling at a reduced speed of 15 km / h to travel a distance of 240 m is approximately 58s. A vehicle traveling at this reduced speed and located at the above distance from the level crossing at the time of the alarm signaling would reach the level crossing only after the gates 2 have been lowered.

The level crossing device is preferably provided with a traffic sign 85 " Light signals ", preferably illuminated by LEDs. Of these traffic signs 85, "Light signals" can be installed more in succession, for example two, being located on columns of traffic signs 155 changing the maximum permissible speed. Traffic light LEDs 85 "Light signals" are preferably switched on when the crossing warning signal is triggered and are preferably switched off when the bolts 2 are triggered, i.e. they are preferably activated for the ringing time.

The level crossing device is preferably provided with a stop light signal 120 "End of all prohibitions" preferably light or mechanical with slats and preferably located on a traffic sign post 85 "Light signals" at a distance of preferably 80 m and 160 m from the rail system 1 crossing barrier. Traffic Sign 120.End of All Prohibitions' is activated when the gates are lowered and allows vehicles to reach the lowered gates at a reduced speed.

The level crossing device preferably comprises a voice unit 24, preferably located on a vehicle stopper post 83, i.e. at a distance of about 80 m from the level crossing, and the voice unit 24 preferably reports text such as " Stop here, camera " on red ". The signaling device system preferably also comprises a second voice unit 24, preferably 80 m upstream of the first voice unit 24. The voice units 24 are preferably turned off when the vehicle sensor 71 detects that the vehicle has stopped prior to the first command signaling 323.

Preferably, an acoustic sensor 213 is also provided near the level crossing, preferably on the camera mock-up column 117, which serves to detect the alarm signaling of the level crossing security device, and preferably comprises a directional microphone 74. speed measurement ”and omnidirectional transmitter 79 for transmitting a signal for at least one of the signs: traffic sign 85 " Traffic signals, vehicle stop 83 until the bolts are triggered. The signal emitted by the omnidirectional transmitter 79 is received by receivers 80 preferably located on columns of the above-mentioned elements whose state is controlled by this signal. Preferably, a traffic sign 90, Speed Measurement 90, is also located on the first column of the dummy of the camera 117.

The system of the signaling device for stopping the vehicles before the railroad crossing barrier system 7 preferably comprises signaling lights 81 in the roadway to highlight the vehicle stopper 83 until the bolts are lowered. The signaling lights 81 in the road are preferably located in the road at the location of the vehicle stopper 83 and are activated with it for the time until the bolts are lowered, and are preferably bounded by a traffic sign 82.

With this embodiment, multiple securing of the railway crossing barrier system 7 is ensured. Advantageously, the first safety measure consists in decelerating the vehicles by the deceleration section 118 using road signs 155 changing the maximum permissible speed from the beginning of the warning system of the rail system 1 until the gates are lowered so that the vehicles cannot pass before crossing gates. preferably it consists of stopping the vehicles by the vehicle stopper 83 until the latches are lowered. Advantageously, the third safety measure consists in locating a vehicle stopper 84 exceeding the maximum permissible speed.

Preferably, the fourth security measure consists in enhancing the vehicle stopper 83 by means of a light sign 201 preferably provided with a "STOP and preferably with a countdown timer 200". All of the above safety measures are effective separately to ensure level crossing safety and optionally applied.

Giant. 8 det. 1 illustrates a block diagram of an acoustic sensor 213 that detects the acoustic signal of railroad crossings and which is preferably solved by a directional microphone 74, preferably located at the focus of the parabola 75 facing the rail signaling device, and preferably the acoustic sensor 213 is tuned. This means that the characteristics of the microphone and its sensitivity in conjunction with the evaluation circuits are set to the characteristic and energetically maximally represented frequencies occurring in the audible warning signal of the level crossing, preferably for each level individually.

This ensures that the detector only responds to this audio signal. Tuning is performed automatically at the instruction of the operator by means of a microprocessor, which in the respective mode of operation evaluates the audible signal of the given railway warning signaling device and sets the characteristics of the evaluation circuits. Sound evaluation is based on Fourier signal development to individual components and their content is compared with the sample to which the acoustic sensor is tuned. When sufficiently matched, the sensor sets its output signal to a state with the meaning that the level crossing warning sound signal has been detected and another signaling according to the present invention is provided providing increased level crossing safety.

Railway audio signals contain at least one, but mostly two dominant frequencies, but there may be more. The audible warning device located on the far side of the passage for the opposite direction also touches the downstream side of the level crossing. This makes it possible to tune the acoustic sensor 213 only to the opposite or to both sides, which further increases the level crossing safety, since further signaling will occur on both sides even in the event of a failure on the railway equipment on one side.

The directional microphone 74, which senses a railroad audible warning signal at the level crossing, is directed to the level crossing and located in the dish 75, and a signal therefrom is applied to the input of the amplifier 76, preferably differential, and further converted to digital signal in the A / D converter 77 This signal is evaluated in the microprocessor 78 and compared to a recorded sample characteristic of the subject passage. In the case of a match, the signal at the respective microprocessor output has a value that expresses the match preferably, wherein the microprocessor output signal can have a significance of 1 after deterioration, preferably lasting for an adjustable reception time of the tuned signal after an adjustable time from the beep. This signal is used to activate other devices, either wired or wireless via the omnidirectional transmitter 79, so that all the pass-through security devices fitted with the receiver 80 can use the signal.

Or, the transmitter 79 is adapted for duplex communication with a receiver 80 also adapted for duplex operation over a mobile network, preferably a local WIFI 87 network. This makes it possible to collect device status information from the status detectors 88. These are preferably registered in the memory of the microprocessors 78 and / or preferably sent over the remote network 89, preferably the mobile operator network to the server 806 of the supervisory center 762. Preferably, the device comprises security sensors to protect the device from theft from the industrial camera 10, which are transmitted to a surveillance console, which can preferably address a potential thief at the time of the crime and detach it with the voice unit 24.
